, Application illed July 30, 1925.

This invention aims to provide a syringe which is so constructed that a medicament may be applied readily to various parts of the human body in a convenient manner, it being possible to substitute one nozzle for another, as occasion may demand.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

lfVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, Without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention, parts being in section; Figure 2 is an elevation showing one of the nozzles, parts being broken away; Figure 3 is an elevation showing another nozzle, parts being in section; Figure 4 is a cross section on the line 11--4 of Figure 3.

The syringe forming the subject matter of this application may be made of any desired material, such as hard rubber, and includes a curved body 1 provided at one end with an enlarged head 2 having a conical recess 3 communicating with a reduced bore 4 extended longitudinally of the body 1 and through a reduced tip 5 at the .outer end of the body, the tip 5 defining an yexternal shoulder 6. The material to be fed through the syringe is inserted into a cup-shaped cap 7 which is threaded at 8 on the head 2, the cap being closed at its outer end as shown at 9.

The numeral 10 marks a nozzle including Serial No. 47,072.

a collar 11 and a reduced end 12, the collar being threaded as at 14 on the tip 5 and being'engaged with the shoulder 6, the nozzle having a conical recess 15 communicating with the bore 16 of the nozzle, the part 12 of the nozzle having lateral outlets 17 which communicate with the bore.

It will be obvious that by rotating the cap 7, the material will be fed through the syringe, to the point of application, the recess 3 directing the material into the bore 4.

A longer nozzle 18 may be employed in the room of the nozzle 10 if desired, the nozzle 18 having a reduced end 19, the bore of the nozzle being marked by the numeral 20, and the conical recess appearing at 21, the butt end of the nozzle being threaded as at 22, for engagement with the tip 5 of the body 1.

The nozzle 23 of the Figures 3 and 4 may be used, upon occasion, that nozzle being somewhat longer than the nozzle 10 of Figure 1. The nozzle 23 has the bore 24, the threads 26 and the conical recess 25 hereinbefore described, the lateral outlets being desi nated by the numeral 27.

T e general construction of the device is such that it will be capable of a wide range of use, and the operator can feed the material, simply by rotating the cap 7.

What is claimed is A syringe comprising a body provided at one end with a nozzle and at the op site end with a threaded feed cap, the body ing curved to dispose the axis of the nozzle approximatel at right angles to the axis of rotation o the feed cap, whereby when the body is held in the hands of an operator, and the feed cap turned, the rotation of the feed cap will have practically no tendency to rotate the body and the nozzle.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature.
